text: In July 2019, a researcher from San Diego-based Stemson Therapeutics, partnered with UCSD, successfully grew his own follicles on a mouse using iPSC-derived epithelial and dermal cell therapy. The hair grew straight and was aligned properly with a 3D-printed biodegradable shaft. The hairs were permanent and regenerated naturally. Stemson intends to enter clinical trials in 2026.
